Ingredients
Directions
Prepare
Gather Catawba grapes before they ripen.
Remove grapes from the stem and wash them.
Extract the juice
Place grapes in a stone jar and set the jar in a kettle of cold water over high heat.
Once the juice is extracted, remove the kettle from heat and strain the grapes.
Sweeten and boil
For each pint of juice, add one pound of the best loaf sugar.
Boil the mixture for twenty minutes.

What each ingredient does
- Catawba grapes
- Provide the juice, along with natural acid and pectin that help the jelly set.
- Loaf sugar
- Adds sweetness and, as it concentrates during boiling, helps the jelly set firm.
The step that matters
Boiling the sweetened juice. Sugar, pectin and acid must be concentrated enough to form a gel. Boiling too briefly leaves the jelly runny, while boiling too long can darken the color and make it stiff.
